SYNTAX

unset name

DESCRIPTION

Use the unset command to delete the setting associated with name. See the set command for a discussion of setting names for variables and expressions.

Do not use the unset command to unset any of the Prism internal variables (beginning with $).

EXAMPLE

If you use the set command to set this abbreviation for a variable name:

set fred = frederick_bartholomew

then you can unset it as follows:

unset fred

In this example, after issuing the unset command, you can no longer use fred as an abbreviation for frederick_bartholomew.
